I am using VSTO in my project with WPF. This is working fine in Excel. But when I install power query in excel2013,my VSTO AddIn is not working. When I disable power query ,my AddIn will work fine.

Need solution for the above issue. Thanks in advance

Check if you have got exceptions in the add-in's code at runtime. That is a possible reason for disabling the add-in. Try to enable logging for your add-in, see Event logging for Office solutions for more information.

Also I'd suggest creating your own log file so, you could analyze it and find the cause at any point.

  • Following error added in event log: Customization URI: file:[Path] Exception: The deployment manifest could not be downloaded because a connection to the network could not be established. Ensure that you can connect to the network, and try again. This is a stand alone application . There is no log present in custom log. – sudeep May 05 '22 at 05:00
  • Such error messages come from a VSTO deployed using ClickOnce installers. See [VSTO ClickOnce ends with "The application could not be downloaded because a connection to the network could not be established."](https://stackoverflow.com/questions/24629215/vsto-clickonce-ends-with-the-application-could-not-be-downloaded-because-a-conn) for more information. – Eugene Astafiev May 05 '22 at 12:02
